1 GENERAL The Contractor shall fulfill each requirement marked M in the margin. The following marks have been used:

Mandatory: Requirements that must be complied with; indicated in the specification in the column on the left hand side (Type) with an M

1.1 Scope The Enquiry and its annexes contain requirements for a new Saturation Communication System, SCS, to be installed onboard the Diving Support Vessel, DSV, HMS Belos of the Swedish Navy. The requirements founded in the Enquiry and in its annexes Technical Requirements (TR), Management Requirements (MR), Logistical Requirements (LR) and System Safety Requirements (SSR), encompass all aspects of the SCS during its life time with regard to function, safety, documentation, logistics, training and quality. With reference to paragraph 1.2, which displays an overview of the diving system, together with a short description of the Saturation chambers System (SCS ), we present the following two statements:

Status: a) The present SCS is not functioning properly and has not been approved by Det Norske

Veritas, DVN. b) The connection from the SAT to the chambers is often uncertain. c) There is no possibility for a total announcement. d) There is no possibility to monitor sounds from all compartments simultaneously. e) The standalone (emergency) telephone system is at the end of its lifetime. f) Some of the cables are new but some of them, together with the penetrators are original

(1985) and has to be replaced.

Requested Action: a) The present SCS needs to be replaced by a new one fulfilling the requisites presented in

TS 4.1 in order to be approved (and certified) by DNV and keep HMS Belos in class. b) The communication network in use today covers the saturation chambers together with

other areas of the Saturation diving system. While the pressurized areas are not served properly by the actual system, it works well in other areas of the diving and submarine rescue systems. The new SCS has to replace the communications in the pressurized environments and related operatively connected areas, in a compatible way with the actual system (shall not interfere or be interfered).

c) The standalone (emergency) telephones have to be replaced with a new one. d) All wires, cable and electronics of the SCS need to be substituted or replaced with a new

system/solution. e) The installation work has to be carried out in such way that the SDS can be operational

within 12 hours. This is due to operational readiness requirements. This does not mean that that the entire SCS installation must be done within 12 hours.

1.2 Description This specification contains neither a detailed description of the where the Communication Network will be installed, nor a detailed description of the communication network in use today. The SDS will be available for inspection by the Tenderer onboard HMS Belos, in the dates and terms presented in the Enquiry document. In this occasion the description part of manual of the communication system installed today will be also available to the tenderer. Moreover, in order to give an overview of the entire system, few images are displayed below and at the end of this document. The schematic does not respect scale, relative position or dimensions neither of the Ship nor of the Saturation Diving System.
